If you understand this life to be like a
dream, you will understand that everything
within it— happiness, wealth, and pleasure,
pain, and suffering—is impermanent and will not
last. You will thus not be so overwhelmed by
different circumstances. You will stay focused
and not be carried away by indulgence in
pleasure, and you will not be much affected by
difficult circumstances.

— Garchen Rinpoche (via dhammatalks)
